NOVELTY - Preparation of zinc sulfide and graphene oxide composite material involves mixing carbon disulfide and ethylenediamine solution until carbon disulfide droplets are completely dissolved to obtain mixed solution, adding graphene oxide to the solvent, ultrasonically processing, stirring for 30-120 minutes, dripping zinc nitrate solution, continuously stirring, transferring mixture to a reaction kettle, cooling to room temperature, centrifuging sample, washing with deionized water and ethanol and drying. USE - Preparation of zinc sulfide and graphene oxide composite material for battery. ADVANTAGE - The method enables simple and energy-efficient preparation of zinc sulfide and graphene oxide composite material. The zinc sulfide and graphene oxide composite material increases energy density of the battery.
